Patented Mar. 18, 1952 UNITED STATES PATENT o FFC-E STEERING MECHANISM FOR THE FRONT z WHEELS OF BABY CAR-RIAGES Christian F. Dennesen, Marblehead, Mass.

Application September 1, 1950, Serial No. 182,808 z Claims. c. 2so` 4s This invention relates to a front wheel steering mechanism for baby carriages, strollers or the like, whereby lateral pressure directed to the handles of the stroller or babv carriage in guiding the stroller or baby carriage, will result in the front wheels automatically turning to facilitate the guiding and handling of the Vehicle, equipped with the present invention.

Another object of the invention is to provide means for stabili ing the front wheels of a baby of parts without denarting from the spirit of the invention as claimed.

Referring to the drawing Figure 1 is a plan view of the front wheel assembly illustrating the position of the mechanism when the wheels are moving forwardly in a Straight line.

Fig. 2 is a plan view of the assemblv, illustrating the positionof the various elements, when the wheels have been slghtly turned.

Fig. 3 is an enlarged elevational view of one end of the assembly, with the wheel removed.

Fig. 4 is a sectional view taken on line 4-4 of Fig. 3. 1

Referring to the drawing in detail, the reference character 5 indicates a front aXle bar to which the Springs 6 of the Vehicle are attached. This bar 5 has its ends connected to the bars 'I arranged at each end of the assembly, the bars 'l being connected to the bearings 8, which bearings move over the stationary auxiliary axles 9 which are arranged in horizontal parallel spaced relation with respect to each other, as clearly shown by the drawing.

The ends of the stationary auxiliary axles 9 are connected by means of the bars IE) that are bolted to the axles. These bars l0 provide supports for the tog le forks H which extend therefrom. These forks Il provide supports for the steering arms |2 which have axles |3 on which the wheels |4 operate.

The steering arms |2 extend rearwardly and connect with the tie rods |5 with which they are associated, the inner ends of the tie rods being connected with the arm l, at I'I. This arm I 6 is substantially T-shaped, as clearly shown by F'gs. 1 and 2 of the drawing, the arm |6 extending to a point overlying the front axle 5, where it is rigidly secured thereto by means of bolts I'I'.

Secured to the forward stationary axle 9, are adiustable spring stops |8 against which the coiled sorings |9 engage. the sorings Ii) also engaging the bearings 8 that move over the forward stationarv axle 9. Thus it will be seen that due to this construction, when the front axle bar 5 is moved to the right or left, due to pressure being directed to the handles of the Vehicle, in guiding the Vehicle, the bearings 8 will be moved longitudinally of the axle 9 on which they are mounted, the snrings |9 acting to stabilize the movements of the bearings and bars 'l connect d thereto. It will also be seen that with this movement, the wheels M will be moved to the angular position as shown by Fig. 2 of the drawing. The spring |9 at one end of the aXle 9 will be comnressed ther bv biasing the spring. It will be obvious that if the Vehicle, or the ront end of the Vehicle is elevated, as when lifting the front wheels over a curb, the action of the comnressed spring I 9 will be to move the bars 'l to their normal pos tions as shown by Pig. 1 of the drawing. With this movement, the wheels hi will assume the parallel position as shown by Fig. 1 of the drawing.

From the foregoing it will be seen that due to the construction shown and described, I have provided a stabilizing means for use in connection with the front wheels of baby carriages or strollers, which will cause the front wheels of a stroller or baby carriage to take an angular position in guiding the stroller or baby carriage to facilitate maneuvering the stroller or bab carriage.

It will also be seen that due to the yieldable construction, the front wheels of the stroller or baby carriage will be stabilized holding the front wheels in parallel spaced relation with each other under normal conditions.

Having thus described the invention, what is claimed is:

1. In a front wheel steering assembly for vehicles, a front axle bar to which the Springs of a Vehicle are attached, a pair o f parallel auxiliary stationary axles, steerng arms pivotally mounted at the ends of the parallel axles on which wheels are mounted, bars slidably mounted on the parallel axles, the ends of the front axle bar being 3 connected to said slidable bars, an attaching bar connected with the front axle bar, tie`rods connecting the attaching bar and steering arms, and coiled Springs mounted on one of said parallel axles engaging said slidable bars, tensioning the movements of the steering assembly.

2. In a front Wheel steering assembly for vehicles, a pair of parallel spaced stationary axles, steering arms supported at the ends of the axles. tie rods connected to the steering arms, an attaching arm to which said tie rods are connected, a front axle bar to which the attaching arm is connected at a point intermediate the ends of the axle bar, bearings mounted on the stationary axles for movement longitudinally therfiof, bars connecting the bearing members to which the ends of the front axle bar are eonnectemstops adjustably mounted on one of said stationary axles, coiled Springs disposed between the stops to which the assembly is connected.
